I have not used a product like this before so was not sure what to expect. I have now used the coffee on three mornings - I think the best thing is the immediate increase in energy. I wouldn't use this at night - although that is recommended - as I think there is a boost of energy which I can feel the whole day. I on't feel unwell or have any bloating with this and it has a reasonably pleasant taste - unlike many coffee substitutes. In all a good product for a great price.
